The lining comprises a. plurality of inter 1522. Serial No. 577,935.

locking sections formed substantially as shown in Fig. '2. The body part4 of these sections is preferably matle. of sheet steel. The lugs .7 atthe backs of these are for engaging the ellgr of the brake band, and thetnrneil over ends 6 and 7 are adapted for iluxihly engaging the adjacentsections of the lining. l rir-tion material 8 is atiaeliml to the bodyof the sections by means of elineli points nresswl inwardly from theinat rial of the back. as indicated at 9. and rlineheil in the frictionmaterial as indi- (lll (i in Fig. l.

M the two cmls t the series of lining sci-[ions are the tcrminal clips10 and 11 ns seen in Fig. 1. These are without side lngs am] earh isbent hackwarilly' over its.

The lining is built up by ruliling a scction at a limo ainl slipping itaroimil the hand win-innfvrentially as it is completed.
